Description

Verfahren zum Vulkanisieren von Kautschuk. Es ist bekannt, daß man Kautschukgegenstände durch Behandeln mit Chlorschwefel in Schwefelkohlenstoftlösung vulkanisieren kann. Man ersetzt bei dieser Kaltvulkanisation auch den Schwefelkohlenstoff durch Tetrachlorkohlenstoff, Benzol oder Benzine, doch geschieht das nach der Literatur seltener.Process for vulcanizing rubber. It is known that one Rubber articles by treatment with chlorosulfur in a carbon disulfide solution can vulcanize. This cold vulcanization also replaces the carbon disulfide by carbon tetrachloride, benzene or gasoline, but this is done according to the literature less common.

Es wurde nun gefunden, daß man aus Chlorschwefel und dem wegen seiner Nichtbrennbarkeit besonders geeigneten Tetrachlorkohlenstoff eine ausgezeichnet wirkende Vulkanisierlösung erhält, wenn man Nitrobenzol zusetzt. Nitrobenzol wirkt stark beschleunigend auf den Vulkanisationsprozeß.It has now been found that one made of chlorosulphur and because of its Non-combustibility particularly suitable carbon tetrachloride an excellent active vulcanizing solution is obtained when nitrobenzene is added. Nitrobenzene works strongly accelerating the vulcanization process.

Folgende Mischungsverhältnisse haben sich als recht geeignet erwiesen, doch kann man für die verschiedensten Zwecke auch andere Verhältnisse anwenden. In 475 Teilen trockenen Tetrachlorkohlenstoff löst man 25 Teile Chlorschwefel und 2 Teile Nitrobenzol. In diese Lösung hängt man die Kautschukartikel bis zur genügenden Vulkanisation ein, wozu bei Gegenständen von geringer Dicke nur sehr kurze Zeit erforderlich ist.The following mixing ratios have proven to be quite suitable, but other conditions can also be used for the most varied of purposes. 25 parts of sulfur chloride are dissolved in 475 parts of dry carbon tetrachloride 2 parts of nitrobenzene. The rubber articles are hung in this solution until sufficient Vulcanization, for which only a very short time in the case of objects of small thickness is required.

Will man zwei Kautschukkörper zusammenkleben, so bestreicht man die Klebfläche mehrmals mit Kautschuklösung, dann mit obiger Lösung und preßt kurze Zeit aufeinander.If you want to glue two pieces of rubber together, you paint them Adhesive surface several times with rubber solution, then with the above solution and press briefly Time on each other.
